COMBINATION-SAW.

Specification of Letters Patent.

Application filed August 22, 1911.

Serial No. 645,353.

m compound tool in which the hand saw is provided with a level, plumband folding square.

The principal object of the invention is to improve the generalconstruction 'of a hand saw provided with a square.

With the above and other objects in view as will be hereinafterapparent, the inven tion consists in general of certain novelarrangements of details and combinations of parts as will be hereinafterset forth, illus- 25 trated in the accompanying drawings, and

specifically claimed.

In the accompanying drawings like characters of reference indicate likeparts in the several views, and: Figure 1 is a side view of a sawprovided with a handle constructed in accordance with this invention.Fig. 2 is a top view thereof. Fig. 3 is a section on the line 33,Fig. 1. Fig. 41 is a perspective view of one of the cover plates of thehandle. Fig. 5 is a perspective view of one of the pivoted bars whichform the square in connection with the saw blade.

This saw is provided with the usual toothed blade whereto is fitted ahandle 40 having a grip 11. The upper part of the handle is providedwith forwardly extending lug 12, while its upper and lower edges arestraight as indicated respectively at 13 and 14. Just forward of thegrip 11 there is provided the usual opening 15, and forward of thisopening is a recess wherein is located a bubble or level vial 16 whichis covered by a suitable plate 17 provided with a central slot so thatthe vial may be observed. The upper edge 13 is parallel with the loweredge 14: and forms a continuation of the back of the blade 10. The upperedge of the handle and back of the blade 10 thus constitute a straightedge. From the lower edge of the handle there extends inward a suitablerecess wherein is mounted a level vial 18 and this lower edge is coveredby a Patented Dec. 5, 1911. I

plate 19 provided with a suitable slot for the observation of the bubblein the vial 18. The vial 16 thus constitutes a plumb vial being at rlghtangles to the back of the saw,

while the vial 18 constitutes a level vial being parallel with the backof the saw.

Gained into each side of the saw handle forward of the opening 15 is asuitable recess for the reception of a cover plate 20, the handle beinggained sufiiciently so that the outer surface of the cover plate isflush with the rear portion of the handle 11. Each of these cover platesis provided at its for-' ward edge with a downwardly and forwardlyinclined lug 21 to the rear of which is a slot 22. Furthermore, each ofthese plates is provided with a forwardly extending lug 23 at its upperedge which corresponds with the forwardly extending lug 12, and eachplate also has a recess 24: in its upper edge for purposes hereinafterto be described, and a niche in its rear edge for the observation of thebubble in the vial 16. Through the lugs 23 and the saw blade 10 passes apivoted bolt 26, which is provided on one side with a wing nut 27. Onthe pivoted bolt is positioned a pair of swinging arms 28, one of thesearms resting on one of the plates 20 while the other arm rests on theplate 20. Each of these arms is provided on one edge with a lug 29 whichis of such size as to readily fit the slot 22 when the arm is turned tothe position shown in dotted lines in Fig. 1. The recess 2 1 is sopositioned that when the arm is turned as shown in full lines in Fig. 1,this lug 29 will engage in this recess. For the purpose of permittingthe arm to lie flush with the grip 11, the upper end of the strip isgained and the upper side of the handle is also provided with suitablenotches 30 which register with the recesses 24 when the cover plates areapplied. For the purpose of preventing the free ends of the members 28from springing outward, there is provided at the rear of the handle aclip 31 having ends 32 which overlap the sides of the handle in spacedrelation thereto so that the ends of the bars 13 may be receivedbet-ween the handle and the ends 32.

In the operation of the device, when it is desired to use the implementas a plumb, the back of the saw is placed against the article to beplumbed and the bubble in the vial 16 observed. When it is desired touse the implement as a level the back of the saw is laid on the objectto be leveled and the bubble in the vial 18 observed. When it is wishedto use the device as a square, the wing nut 27 is loosened slightly, andone or the other of the arms swung around, the arm being moved upwardlyso that as it swings forward into position the-lug 29 will strike thelug 21, thus bringing the arm slightly upward and permitting the arm toslide over the forward edge of the plate 20 and the lug 29 to engage inthe recess or slot 22. WVhen it is wished to use the device as a squareit being observed that the recess and the opening for the bolt 26 are sopositioned that when the arm is in position, as shown in dotted lines inFig. l, the forward edge thereof will be at right angles to the back ofthe saw. Of course, it will be obvious that the reason for employing twoof these arms is that in some instances it is necessary to turn a squareover so that it is essential that there be two arms instead of one. Thedevice may also be used to lay off bevels by swinging one of the arms 28around to -a suitable position and locking the same wit-h the nut 27 Itis preferred, that the saw be equipped with a scale as indicated at 33and that each plate be provided with a suitable scale of angles 34.

There has thus been provided a simple and eflicient device of the kinddescribed, and for the purpose specified.

It is obvious that many minor changes may be made in the form andconstruction of the invention without departing from the materialprinciples thereof. It is not, therefore, desired to confine theinvention to the exact form herein shown and described, but it is wishedto include all such as properly come within the scope of the appendedclaims.

Having thus described the invention, what I claim as new, is

1. In a compound tool of the class described, the combination of ablade, a handle therefor, said handle being provided with a recesstherein adjacent its forward edge, and a second recess adjacent itsupper edge, a bar pivoted to the handle above the first and forward ofthe second recess, and provided with a lug adapted to fit either of saidrecesses, and a clamping nut for securing said bar in adjusted position.

2. The combination with a saw handle, of a cover plate therefor providedwith a slot adjacent its forward edge, and a downwardly and forwardlyextending lug in alinement with said slot and depending from the forwardedge, said plate furthermore having a recess in its upper edge, a pivotbolt extending through the handle and plate, an arm pivoted on saidpivot bolt and provided with a lug fitting said recess and slot, aclamping nut on said pivot bolt for securing said bar in adjustedposition, and a clip having an end for engagement with the end of thebar opposite the pivot.

In testimony whereof I hereunto aifix my signature in presence of twowitnesses.
